Title: Magnetic disk device controlling method
Inventor: HIBINO YOZO
IPC: G11B21/10
Filed: 1989-05-19
Abstract: PURPOSE:To obtain specified positioning accuracy to a target track in a prescribed time by adjusting an initial operation amt. of a position control and a cut-off frequency in accordance with an initial position and an initial speed at the time of shifting from a speed control to the position control according to a position or speed. CONSTITUTION:The speed is feedback-controlled by the speed control 8 in order to achieve a target speed in accordance with a difference between the target track and present track, and hence a magnetic head 4 is moved to the target track. Then, a position feedback control is performed by the position control 9 in order to make a position signal zero, so that the magnetic head 4 is positioned in the target track, whereas the shifting condition from the speed control 8 to the position control 9 is decided in advance with a position or speed, and this is monitored by a shifting control 10, and at that time, a changeover switch 11 is changed. Then, the initial operation amt. of the position control and the cut-off frequency are adjusted in accordance with an initial position and an initial speed at that time, so as to maintain the position control in its specified performance. By this method, the specified positioning accuracy to the target track in the prescribed time can thus be obtained.

Title: Flexible printed board for bending
Inventor: OTA HITOSHI
IPC: H05K1/00
Filed: 1990-05-15
Abstract: PURPOSE:To prevent the disconnection of a belt type circuit part for an earth line when bending and stretching are repeated, by branching the belt type circuit part for an earth line of the part to be bent in a U-type, into a plurality of a narrow belts. CONSTITUTION:A wide belt circuit part 2 for an earth line in a metal foil circuit pattern is branched into a plurality of narrow belts, at a bending part A, thereby forming a branching circuit 3, whose width is set nearly equal to the width of a belt type circuit part 1 for a signal line. In this case, in order to keep electric characteristics as the earth line, the sectional area of the total branching circuit 3 is set nearly equal to the sectional area of the belt type circuit part 2 for an earth line which is not branched. Hence the stress concentration on the bending part of the belt type circuit part 2 for an earth line is dissolved, and the stress is dispersed on the whole part of the metal foil circuit pattern, so that the generation of the situation that disconnection concentrates on the belt type circuit part 2 for an earth line can be evaded.

Filed: 1999-04-30
Abstract: PROBLEM TO BE SOLVED: To obtain a coil which can be stably stored and transported by inserting spacers between metallic band at portions smaller in sheet thickness. SOLUTION: A metallic band different in thickness in the width direction is wound into a coil 1, and a spacer 4 is inserted between the metallic bands of a portion 3 smaller in thickness of the coil 1 or in the total length of the coil or partially in the longitudinal direction of the coil, or the metallic band of the portion 3 smaller in thickness is dimpled. Inserting the spacer 4 compensates for the difference in thickness and makes it possible to place the coil with the hole horizontal on a flat floor. The spacer 4 can be inserted either in the total length of the coil 1 or partially in the longitudinal direction of the coil 1. When the spacer 4 is inserted in the total length of the coil 1, the spacer 4 with thickness for compensating for the difference in sheet thickness of the coil 1 is used.
